Field experiment was carried out in the experimental field of Horticulture department, IGKV, Raipur (Chhattisgarh) during the year 2003–2006. The experiment was laid out in Randomized Block Design with four treatments i.e. 1) Red plastic mulch, 2) Black plastic mulch, 3) White plastic mulch and 4) Surface irrigation without mulch was treated as control (recommended cultivation). The experiment was laid out to assess their importance as mulching component in Tomato cultivation. The study revealed that drip irrigation with red plastic mulch of 25-micron thickness showed superior yield and yield attributing characters as compared to other mulched treatments. The yield of tomato in red plastic mulch, black plastic mulch, white plastic mulch and control plots were 335.75, 324.62 312.18 and 230.72 q/ha respectively. These results showed that the red, black and white plastic mulch increased the yield of tomato by 45.52, 40.06 and 35.30% respectively over the control. The vegetative growth flowering and quality parameters were best under red-mulched plants as camped to control. Water use efficiency and water savings were found to be highest under red plastic mulch and lowest under non-mulch condition. The net income was recorded higher under red plastic mulch (Rs.85800) and lowest in without plastic mulch (Rs. 38020). Similarly benefit cost ratio was also recorded most economical in red plastic mulch as compared to non-mulch condition.
The present investigation entitled as “Effect of bio-fertilizer on growth, yield and quality of strawberry (Fragaria x ananassa Duch) cv. Nabila under net tunnel” was carried out at the Research Farm of the Center of Excellence on Protected Cultivation and Precision Farming in Net Tunnel at IGKV, Raipur (C.G.) to assess the impact on bio-fertilizers on growth parameters, yield and quality of strawberries. The investigation was laid out with 12 treatments which replicates thrice under randomized complete block design. The trial had 12 different combinations of bio-fertilizers. Treatment T5 RDF + Azospirillum (@7 kg / ha) + Phosphate Solubilizing Bacteria (@6 kg / ha) has been recorded best for growth parameters i.e. plant height, plant spreading in East-West and North-South directions and number of leaves per plant, whereas the lowest value for the same was noticed in treatment T0: RDF (Contorl). Earliest flowering, fruiting and fruit maturity was seen under the treatment T11: RDF + Azospirillum (@7 kg/ha) + Phosphate Solublizing Bacteria (@ 6kg/ha + VAM @10 kg/ha), while the late flowering, fruiting and fruit maturity was observed under control. Flowering and physical parameters of fruit i.e. number of flowers, number of fruits per plant, fruit of length, diameter, volume and weight of fruit were significantly influenced under the treatment T11: (RDF + Azospirillum (@7 kg / ha) + Phosphate Solubilizing Bacteria (@6 kg / ha) + VAM (@10 kg / ha) whereas, the minimum value for the same was observed under control (T0). As regard yield, the yield (355.84 q/ha) was obtained under the treatment T11, which was found highest among rest of the other treatment. Moreover, control registered the lowest yield (196.23 q / ha). The treatment T11 (RDF + Azospirillium @ 7 kg/ha + Phosphate Solubilizing bacteria (@ 6 kg/ha) + VAM (@10 kg/ha) registered highest benefit cost ratio (4.20:1), while the value (2.20:1) was observed in RDF + control.
